English actress and activist Emma Watson sparked pregnancy rumors following her appearance at a recent awards night in a head-turning recycled outfit, which teases her sexy back but covers her entire tummy.

The "Harry Potter" alum was in the inaugural Earthshot Prize: Repairing Our Planet awards on Sunday to present an award for remarkable individuals doing their part to save the planet. The event was founded by Prince William, the Duke of Cambridge, with David Attenborough in 2020.

To match the theme of the ceremony, Watson, 31, donned a flowing white tulle gown, which was recycled from 10 dresses from Oxfam, and paired the stunning ensemble with black trousers and chunky boots, the Birmingham Mail reported.

Her bizarre outfit has earned praises online, with one user writing on Twitter, "I adore Emma Watson's outfit. Completely adore it."

However, the same attire caused a stir online, with many asking if her top was made to cover her bulging pregnant tummy. 

An account user named Spartan Goddess tweeted to ask: "Is Emma Watson pregnant? Is that why she's wearing that strange outfit?"

Another netizen also wondered, "Is Emma Watson pregnant? That dress."

"Hate to be one [of] these people but Emma Watson is so pregnant," another Twitter user posted

So far, the rumors remain to be speculation and nothing has been confirmed. 

The "Noah" star had previously feigned pregnancy as part of her method acting approach for the epic biblical drama film by Darren Aronofsky, where she played the role of Noah's adopted daughter-in-law Ila, who carried twins in her belly, according to Techno Trenz.

Watson admitted it was hard for her to wear her maternity suit during the tapings but decided to use it anyway to best understand her character. She noted her designer had prepared a suit that weighed one child.

“It wаs intense,” Emma said while reflecting on the hardships pregnant women and mothers go through. “Women аnd motherhood, аnd whаt they do, hаve а whole new meаning for me.”

The gender equality advocate rose to fame as Hermione Granger in the "Harry Potter'' film series and has since used her platform to promote her advocacies, including sustainable fashion and environmental living, the Daily Mail noted.

In 2011, she collaborated with Italian designer Alberta Ferretti for a green capsule collection called Pure Threads. It came a year after her 2010 Vogue interview revealed she is open to working with ethical brands for free provided that they go green. 

She then expanded her reach, setting up an Instagram account and made The Press Tour in 2017 as she documented herself in sustainable outfits to promote her cause.
